Deadline has revealed today that actor Colin Salmon (Resident Evil) will be playing the role of Walter Steele, Oliver Queen’s new stepdad, who married Oliver’s mother, Moira, in the years that her son was lost at sea.

“A commanding, upper crust man, Walter is Moira’s second husband; he married her after Robert was declared legally dead — and he’s understandably interested in whether or not Robert is literally dead. MAJOR RECURRING GUEST STAR.”

The cast is almost completely revealed as the show gets closer to shooting in Vancouver!
